Rock:W is up, S is down, A is left, and D is right. Paper:I is up, K is down, J is left, and L is right. Scissors:UP ARROW is up, DOWN ARROW is down, LEFT ARROW is left, and RIGHT ARROW is right. Rock targets Scissors and its assassin is Paper Scissors targets Paper and its assassin is Rock Paper targets Rock and its assassin is Scissors The goal is to beat your target without being hit by your assassin. Also if you touch the red blocks, then you die.
I was inspired by the Rock Paper and Scissors game in the Gamescape (which was in Artscape) at Lutherville.
